anybody get the january 2010 issue of the jp magazine? it has a jeep 4.0 motor that has been stroked and a turbo added to make 690hp and 777lbs of tourqe!!!!!!!!!! and they said it would makee more with bigger injectors? thats just crazy!!!

 

I'm sure there is a laundry list of other parts in that bad boy wonder how much that cost to do .

 

I saw it. Impressive, but unrealistic for most of us.

 

True. Realistically I would like 10-15 more horses.

 

yeah that article was ridiculous, it has roller cam, high volume oil pump, bored throttle body, alum. head, i think it is also bored not just stroked, etc.

 

yea it is alot of work and money but it is cool to know it could be done!!!

 

impressive #'s. I would question reliability and streetability too.

 

They were quick to mention it will be used for towing and have to live on pump gas. So I would expect lower numbers just to keep it livable. I don't think it had an aluminum head though. Bored .060 over and a 5 liter crank set. Very special and specific block machining, head work, gasket matching of the intake manifold and the throttle body, prototype throttle body, Yella Terror roller rockers. They didn't mention what fuel pressure they were running to get 693hp which maxed out their injectors. And other than add-on fuel/spark management, they were using the stock computer.

They did pull the head after their dyno runs and the pistons and cylinders were in good shape. Turn down the boost and fuel and I can see this thing running 450-500hp reliably.

 

I seen that. They are planing on using that engine for towing. I wonder how much fuel that thing is going to eat.

 

yea just 400-450hp and 500lbs of tourqe would be retarted and reliable? that would be great!!! still alot of $$$ though

 

Did they mention strengthing the frame and/or the drive shafts? With that much power stock will not hold up.
